Influence of Applied Stresson Temper Embrittlement of 2.25Cr-1Mo Alloy Steel;

作用应力对2.25Cr-1Mo合金钢回火脆性的影响

67 MPa applied stress at 468 ℃ for 200 h has been carried out.

67 MPa的作用应力下,进行了468℃×200h的等温回火脆化试验。

The orthogonal direct shearing experiments about building sand, standard sand, silt and clay on concrete interface, smooth and rough interface of the metals, using DSR 1 type computer high pressureshear system, have been conducted in the paper.

通过在DRS 1型微机高压直残剪试验系统上所进行的建筑砂、标准砂、粉土和粘土与砼、金属光滑、金属粗糙界面的正交直接剪切试验研究表明 :高应力作用下土体与刚度较大的界面的剪切应力 剪切位移曲线呈现出应变硬化的特征 ,与低应力作用下土与不同结构剪切特性存在明显的区别 。
