摘要
本文对Fe-B基微晶材料的反玻璃化热处理条件,组织精细程度和硬度(HV_(RT),HV_(500℃),HV_(600℃))三者之间关系作了系统的研究。在晶粒尺寸不太小时,HV与d^(-1/2)呈直线关系,但在超细晶粒尺寸时,直线发生偏离。
The hot hardness at elevated temperatures 500 and 600℃ of Fe-B
microcrystalline material with relation to the devitrifying annealing and structural
refinement has been examined. It seems to be a linear relationship between hardness
and reciprocal square root of mean crystallite size not so fine, and to diverge from
that for the ultrafine crystallites.
