摘要

研究了含超细颗粒烧结钢淬火过程中马氏体相变的规律。由于孔隙的存在有利于马氏体在孔隙表面的形核，多孔奥氏体对转变变形的阻力较低，因此发现孔隙的存在加速了马氏体转变的过程。因此，孔隙率的增加导致马氏体起始温度的升高。同时，超细颗粒的引入不影响马氏体的起始温度。

Martensitic transformation in sintered powder steels with ultrafine particles

The authors investigate the patterns of martensitic transformation during quenching of sintered steels containing ultrafine particles. The presence of porosity in sintered steels was found to accelerate the process of martensitic transformation due to the facilitated nucleation of martensite on the pore surfaces and the lower resistance of porous austenite to transformation deformations. As a result, an increase in porosity leads to an increase in the martensite start temperature. At the same time, the introduction of ultrafine particles does not affect the martensite start temperature.
