    摘要:

    在X2001應(yīng)力分析儀上采用懸臂梁加載法測(cè)試了可以用于鈹?shù)腦射線應(yīng)力測(cè)試的5個(gè)衍射晶面的應(yīng)力常數(shù)。結(jié)果表明,鈹?shù)?個(gè)衍射晶面的應(yīng)力常數(shù)差異較大，在進(jìn)行X射線應(yīng)力分析時(shí)．應(yīng)采用相應(yīng)衍射晶面的應(yīng)力常數(shù)，才能獲得準(zhǔn)確的應(yīng)力分析結(jié)果。由于X射線對(duì)鈹有較大的穿透深度，必須考慮X射線穿透深度對(duì)應(yīng)力常數(shù)標(biāo)定的影響。

    Abstract:

    The X-ray stress constants of five crystalline planes of beryllium were measured by using a cantilever beam loading method on X2001 stress analyzer. The results show that the X-ray stress constant of each plane in beryllium is different, so the X-ray stress constant corresponding to a diffraction plane must be adopted in order to acquire the exact stress value on X-ray stress analysis. Because of the rather large penetrate depth of X-rays into beryllium, that effect on X-ray stress constant measurement must be taken into account.
