x 射线应力测定方法是一种无损检验法,其特点是可测定微区的应力。测定原理从前就知晓,而且还用来测定实物机械构件的残余应力。以往,x 射线光谱法一直是采用平行电子束法。1973年日本材料学会 x射线强度部委员会归纳整理出铁素体和马氏体系钢铁材料的 x 射线应力测定标准也是一般的测定方法。1977年,在测定标准中又补加了一种对现场的实体试样测定更为合适
X-ray stress measurement method is a non-destructive test, which is characterized by the determination of the micro-area stress. The principle of measurement has been known before, but it is also used to determine the residual stresses of physical mechanical components. In the past, x-ray spectroscopy has been the use of parallel electron beam method. In 1973, Japan Society of Materials x-ray intensity ministries and commissions summarized the ferrite and martensitic steel materials x-ray stress measurement standard is a general method of determination. In 1977, it was more appropriate to add an on-site physical sample measurement to the measurement standard
