Mechanical properties and damage constitutive model of mud shale under different drilling fluids immersion [PDF]
, 2023 In the process of shale oil and gas drilling, the long-term erosion and weakening of drilling fluids promotes the extension and expansion of micro-fractures on mud shale, which leads to the reduction of rock mass strength and seriously threatens the ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

随机变幅载荷下海水腐蚀疲劳裂纹扩展速率的断裂力学参量选择 [PDF]
, 1994 ＃ 本文就随机变幅载荷下疲劳裂纹扩展速率的断裂力学参量的选择进行了分析;并与压机变幅载荷下焊接接头海水腐蚀疲劳裂纹扩展试验数据进行了比较;由此认为采用△K_(rms) ;作为断裂学控制参量是可取的;并且认为用常幅循环加载下的焊接接头海水腐蚀疲劳裂纹扩展速率曲线代替以△K_(rms)为参量的随机变幅加载下的裂纹扩展速率曲线;以此来估算其海水腐蚀疲劳裂纹扩展寿命;在工程应用上不仅方便可行 ...
