Experimental research on the fatigue crack growth behaviour of Q420C

Chun-Jun Chen et al.

Summary: This paper presents an experimental and theoretical study of the fatigue crack propagation behavior of Q420C steel. The results show that the incremental polynomial method is more suitable for calculating the crack growth rate compared to the secant method. The rate curves of Q420C steel exhibit a clear load ratio effect, which can be accurately described by models such as Walker's model. The theory of plasticity-induced crack closure cannot explain the effect of load ratios. In addition, the applicability of BS7910 to Q420C steel is verified, and the different degrees of conservatism of the recommended design curves in BS7910 are demonstrated.

Additive manufacturing of functionally graded inconel 718: Effect of heat treatment and building orientation on microstructure and fatigue behaviour

Saeede Ghorbanpour et al.

Summary: This paper investigates the effect of post-process heat treatments on the microstructure and fatigue crack growth behavior of functionally graded (FG) laser powder bed fusion (L-PBF) Inconel 718 (IN718) superalloy. The study shows that heat treatments can enhance the damage tolerance of L-PBF IN718 to the level of wrought material. Additionally, the effect of roughness-induced crack closure is found to be dependent on the build orientation.

Effect of microstructure on fatigue crack growth of wire arc additive manufactured Ti-6Al-4V

Yong Xie et al.

Summary: This study investigates the effect of microstructure on fatigue crack growth (FCG) behavior in WAAM Ti-6Al-4V material. It was found that Delta KT plays a significant role in influencing the FCGR. Samples with different grain boundary alpha structures exhibit different FCG behaviors, with continuous alpha GB structures showing anisotropy.

Effect of microstructure on short fatigue crack growth of wire arc additive manufactured Ti-6Al-4V

Yong Xie et al.

Summary: This paper investigates the short fatigue crack behavior in wire arc additive manufactured Ti-6Al-4V, finding that cracks in colony microstructure have the largest fluctuation range while cracks in duplex microstructure have the smallest. The crack growth behaviors are influenced by different factors such as Schmid factor, burgers orientation relationship, and interfaces within the microstructure.

Microstructural evolution and anisotropic mechanical properties of Inconel 625 superalloy fabricated by directed energy deposition

Yunlong Hu et al.

Summary: The microstructure and anisotropy of mechanical properties in Inconel 625 superalloy prepared by directed energy deposition were studied, revealing significant differences in tensile properties and fatigue crack growth behavior between horizontal and vertical samples due to the anisotropic microstructure. The horizontal sample showed higher yield strength and ultimate tensile strength, as well as lower fatigue crack growth rate, but lower elongation compared to the vertical sample.

Effect of microstructure induced anisotropy on fatigue behaviour of functionally graded Inconel 718 fabricated by additive manufacturing

Saeede Ghorbanpour et al.

Summary: This study investigates the effect of microstructural anisotropy on the fatigue crack growth behavior of functionally graded Inconel 718 fabricated through laser powder bed fusion. Different manufacturing parameters result in varied microstructures, and only the lower laser power L-PBF Inconel material showed comparable fatigue crack growth behavior to wrought heat treated material. Additionally, a new approach of controlling crack length was employed for graded specimens to investigate the crack growth rate as a function of local microstructure.
