Metalurgija prahov je že dodobra uveljavljen proizvodni proces v industrijah z velikoserijsko proizvodnjo. V avtomobilski industriji so tako izdelani npr. različni manjši nosilci kompleksnih oblik, zobniki oljnih črpalk in njihova ohišja. Napredek tehnologije in materialov pa že nakazuje prodor kovi ...

The main focus of this study was to determine how heat treatment affects the dynamic properties of sintered steel. All the specimens were made of the DIN SINT-D30 metal powder, but only half of them were additionally heat treated. Flat specimens were cold pressed and sintered. The second set was add ...

Al-based alloyed powders, appropriate for the sintering procedure (powder metallurgy, P/M) contain the alloying elements with a high solid solubility in Al, enabling reaction and liquid-phase sintering. They are surface oxidised because of a high affinity of Al to oxygen. Besides, this type of powde ...
