Study on properties and plastical deformation of austenite - bainite steel
奥贝双相钢力学性能及塑变分析
The results show that with the increase of loads , the mass loss of roller increases considerably , with the increase of roller ' s hardness , the main wear mechanism changes from plastic deformation wear to ploughing wear
结果表明，随着外加载荷的增大，轮子磨损加剧，随着轮子硬度增加，主要磨损机理从塑变磨损转变为犁沟磨损。
The microscopic plastic deformation of the local crazes cause the change of crack opening loads . therefore , the fatigue crack closure concept could be introduced . a crack closure model of mdyb - 3 pmma were recommended and phenomenologically formulated for positive and negative stress ratios separately , according to the testing results of fatigue crack propagation
本文讨论了有机玻璃疲劳裂纹扩展机理，提出，银纹的形成是裂纹形成和扩展的基础，从微观上解释了裂纹形成和扩展的原因，并结合金相分析结果，明确提出塑变诱导闭合和粗糙诱导闭合是有机玻璃疲劳裂纹面闭合的两个主要原因，成功的解析了裂纹面的闭合现象。
