PM Opportunities in Extended Electrification
and e-Mobility Applications by Soft Magnetic
Composites

by Dr. Lars-Olov Pennander

SMC Business Development Manager

Höganäs AB, Sweden

Abstract:

Soft Magnetic Composites – SMC are powder components very closely related to sintered PM components regarding the production of components. SMC have good magnetic properties and share the unique forming features from the normal PM manufacturing.
Electrification in automotive is now turning into a new phase after a long time of very slow and very limited establishment. Suddenly your neighbor seriously start to talk about buying a HEV or even a pure electric car, this was not possible only 10-15 years back in time and now this trend seems to be confirmed. This will cause changes of positions on the automotive market that will rise new demands for many of the components and systems that in the future will be requested by the automotive OEM’s.
How can SMC possibly create values in extended electrification and e-mobility? The presentation will identify the major opportunities and show examples of how SMC Technology can be competitive in these new applications.

Development of High Performance Injection
Molded Ti-6Al-4V Alloy Compactsfor Aero-
space Application

by Dr. Hideshi Miura

Professor, Former President of Japan Society of Powder Metallurgy (JSPM)

Department of Mechanical Engineering, Kyushu University, Japan

Abstract:

Ti-6Al-4V is the most common Ti alloy and has been used in various industrial fields including aerospace and power plant because of their high tensile strength, high fatigue strength and light weight. However, their low thermal conductivity, high hardness and low Young’s modulus make them difficult to produce the complicated shapes via machining. On the other hand, metal injection molding process offers net shape production, high design flexibility, and high cost efficiency, which is useful for forming the materials with poor workability such as Ti alloys.
In our previous studies, the injection molded Ti-6Al-4V alloy compacts were improved the properties by addition of third elements such as Cr and Mo, and they showed high tensile strength and high elongation comparable to wrought materials. However, the fatigue strength was significantly lower than that of wrought materials. In order to improve the fatigue strength of injection molded Ti-6Al-4V alloy compacts, refining of microstructure was treated by addition third elements including TiB2 powders. Eventually, we obtained the same fatigue strength as that of wrought materials. In addition, the relationship of grain size and fatigue strength showed good agreement with Hall-Petch relations.

Furnaces are an Essential Parts of Powder Metallurgy

by Mr. Ingo Cremer

Chief Executive Officer

CREMER Thermoprozessanlagen GmbH, Germany

Abstract:

Either reduction, annealing and sintering is done. Different types had been developed. For the iron based powder, press and sintering belt furnaces are the backbone of the industry. It can be divided into two families: Nitrogen/Hydrogen gas or Endothermic gas furnaces. It is shown how modern furnaces are equipped with special accessories to match with modern process demands as sinter hardening or modern ways of delubrication. New approaches for higher sintering temperatures are shown for longer belt life or even getting rid of belts in roller or walking beam furnaces.

Modern P/M application requires sometimes pure hydrogen atmosphere with more than 1.350°C. Here MIM or Fuel cell is mentioned and equipment for such application in large scale is shown. MIM is now a mature technology, so reliable high capacity equipment is essential for CCC, Defense, Medical or Automotive industry is important. A cross view to Nuclear fuels is made. Refractory metals as Mo and W are produced in a powder metallurgical way. The powder is produced in different reduction steps. Their carbides are made in carburizer furnaces up to 2.500°C. P/M suffers here and there density issues! With Hot isostatic pressing, we can overcome end-user concerns of aerospace or medical industry.

Industry 4.0 – The Challenge for the PM Industry from the Viewpoint of a Press Maker 

by Mr.Josef Spensberger

Deputy Managing Director

DORST Technologies, Germany

Abstract:

Smart Factory and Smart Production are the keywords of the emerging development for production facilities in connection with Industry 4.0 and IOT. The production equipment as such is no longer in the focus, but the production process and, consequently, the article to be produced. This development will be a great challenge for both the suppliers of machinery and the users. Data recording, data analysis and the derivations resulting from the latter are the first steps being realized at present.

Modern machinery is already equipped with extensive sensor technology. Two options of how to use these data will be indicated. The first option is evaluating these data within the scope of a status analysis and to determine active measures to avoid machine standstill. The second option is to enrich the data by additional information such as, e.g. weight and height, and to send them directly along with the component produced.
