EXTRACT FROM THE SESSION ENERGY EFFICIENCY IN HEAT TREATMENT

The session brought together a very interesting series of four lectures on the subject of energy management in heat treatment operations, each describing a particular approach. This session highlighted the different levers that can be used by an industrial company to optimize its energy bill, these levers calling for very different and often complementary strategies.
The renewal of thermal equipment by using new technologies is of course part of the range of means of action. Thus, GRDF (Cyril CROCGAILLARD and Laurent ANTOINE) presented GRDF's policy in favor of innovation in gas technologies and the results of the qualification program for NOXMAT self-recovery burners.
The optimization solutions by modeling of heat exchanges, control and regulation, exploitation of industrial field data were developed by CMI (Jean-Christophe MITAIS). Each industrial situation is thus evaluated using industrial data in order to determine new thermal operating configurations.
Pierre-Jean MARCHAIS detailed the approaches developed by MANNESMAN PRECISION TUBES to improve the efficiency of tube heat treatment furnaces. A very pragmatic approach, based on a thorough review of real needs and questioning of old choices in terms of heating strategy
has produced spectacular results on existing installations, without the need for heavy investments.
Finally, Daniel ZIMERMANN (AICHELIN Group) presented the developments in the architecture of heat treatment furnaces in the automotive sector. The integration of these heat treatment facilities into the site, both upstream and downstream, is a powerful lever for progress, as the price conditions for access to energy, which vary according to geographical zones, determine the competitiveness of a given solution.
The integration of waste energy recovery technologies (ORC type technologies, etc.) can also be examined when the price per kWh exceeds a certain threshold.
The subject of energy efficiency had not been addressed in recent years in the A3TS Congress. At the end of this session, it was noted that manufacturers can approach the problem with multiple angles of attack and that significant results can be obtained quickly without heavy investments being necessary.
The sharing of industrial experiences and best practices and the associated results is probably a determining factor in accelerating decisions, achieving significant gains in consumption (gas and/or electricity) and thus contributing to improving the competitiveness of companies in the sector.
A date has been set to continue discussions on this topic at the next congress. The project to create an "Energy" commission within the A3TS was also mentioned.

EXTRACT FROM THE SESSION ADDITIVE MANUFACTURING

The finishing of parts from additive manufacturing is a very important issue for this process, leading to many questions. The success of the A3TS days in Colmar dedicated to "treatments on metal parts from additive manufacturing" which brought together 130 people in December 2017 led the scientific council of the A3TS to propose a special session of our 45th congress on this subject. The aim was to find the most outstanding conferences to follow the evolution of techniques after a few months, and to focus on emerging processes.
A full house welcomed the first lecture given by Eric NIVET from CETIM on the influence of heat treatments on "the
mechanical properties of a 17- 4PH stainless steel produced by LBM (Laser Beam Melting) additive manufacturing". The main characterizations concern the mechanical properties including those of traction. It is a question of characterizing the mechanical behavior of the material resulting from the additive manufacturing
with respect to the reference heat treatments carried out in conditions. There is a lot of unacceptable heterogeneity in
the results at breakage, due to the presence of defects (lack of material, welding defects). Adapted heat treatments,
associated with hot isostatic compression considerably reduce the defects.
Jean-Yves THIEULEUX (CURTISS) then presented the "Fatigue results of the application of shot and laser peening on
TI-6AL-4V and 316L specimens" from additive manufacturing. Without finishing treatment, SLM titanium alloys show an improvement in their fatigue performance
when undergoing "superfinishing" or when machined, with the cause being melt failures or inflated particles. Shot peening on raw parts almost always results in increased residual compressive stresses.
For stainless steel specimens, even better notch results than forged steel are achieved (with even an infinite life at 400 MPa). The IRT M2P is also very present in the field of the finishing of additive manufacturing parts with "the architecture of the AFTER project
ALM" presented by Joffrey TARDELLI (IRT M2P). This project brings together 27 companies and 2 academic laboratories since November 2016 by developing several techniques in parallel, using among others mechanical, laser, chemical and electrochemical interventions. Anthony SPICA (CIRIMAT Toulouse) presented an illustration with electrochemical plasma polishing of aluminum alloys.
This little known technology combines a physical action linked to the formation of a plasma around the totally immersed part with an electrochemical action. Chloé ROTTY (post doc IRT M2P) and Estelle DRYNSKI (doctoral student IRT M2P) then presented the work they have conducted at the Institute
UTINAM on "Electropolishing solutions on materials from additive manufacturing". Although known for a long time, this technology
had not been the subject of work for a long time and the high level of requirement concerning the final result led to a thorough study of many parameters, both in terms of the composition of electrolytes and the conduct of the processes, and allows to obtain very good results by conferring smooth and shiny aspects on 316L samples. This work is extended to nickel-based steels and titanium alloys.
The work of Jordan RIGAUD (LIEBHERR AEROSPACE) carried out at CIRIMAT reminds us that the optimization of the various heat treatments is based on a relevant analysis method that he describes as an "Original method of optimization of post-fabrication heat treatments based on a thermo-mechanical approach". The behavior of AS7G06 specimens in 4-point bending is used to define the zones of interest in the metallurgy of the different processing modes, to evaluate the amplitude of the mechanical state-phase transition couplings.

Eric NIVET (CETIM) concluded the session with a "Comparative analysis of 17-4PH parts made by different suppliers in
laser fusion on powder bed". From identical specifications proposed to five different manufacturing platforms, the results are analyzed on a very large number of characteristics such as macro and microstructure, density, sensitivity to heat treatment, stress states, mechanical properties...

THE INNOVATION AWARD

MATERIALS TREATMENT sector
It is by presenting its Statop 704 4-loop controller solution coupled with the CPS Touch HMI that PYROCONTROLE won this award. A great reward for a brand new controller that enriches the Statop 500 and 600 controller range launched at the end of 2017.
The advantage of this coupled solution: to associate a high-performance controller that adapts to any type of application with a HMI. It offers 4 independent PID temperature loops and additional inputs/outputs for multi-zone control. Associated with the CPS Touch,
the operator can visualize the whole process, record data, configure the device or modify alarms. The interface is available in several formats.
