自从1946年瑞士伊尔曼(R.Irmann)首创烧结铝之后,铝粉末冶金技术很快引起了先进工业国家的注意,人们沿着两个方向进行了大量研究:一是铝粉末冶金变形加工制品,二是机械零件制品。前者是三十多年来的主攻方向,而后者,在发展初期由于制造技术方面的困难而停滞不前,但是,近十多年已有突破,并获得了迅速发展。 Since the first sintered aluminum by R. Irmann in 1946, aluminum powder metallurgy technology quickly attracted the attention of advanced industrial countries. There have been many studies in two directions: one is the deformation processing of aluminum powder metallurgy Second, the mechanical parts products. The former has been the main direction for more than three decades. The latter, which was stagnating in the early stages due to manufacturing difficulties, has made breakthroughs in recent decades and has achieved rapid growth.
