Influence of pulse energy on surface integrity of AZ31 magnesium alloy processed by femtosecond laser shock peening

Autor: Tong Zang, Zongshen Wang, Lei Chen, Meng Kong, Shan Gao, Harry M. Ngwangwa, Lihua Zhu, Wenhui Yu, Hongyu Zheng

Publikováno v: Journal of Materials Research and Technology, Vol 25, Iss , Pp 4425-4440 (2023)

Compared with traditional laser shock peening by nanosecond pulse laser, femtosecond laser shock peening (FLSP) exhibits superior flexibility and efficiency since it can be carried out directly in air without any ablative or confinement layers. In th

Effects of constrained groove pressing and temperature-assisted ultrasonic shot peening on microstructure and mechanical properties of a two-phase Mg–Li alloy

Autor: Meng Kong, Tong Zang, Zongshen Wang, Lihua Zhu, Hongyu Zheng, Shan Gao, Harry M. Ngwangwa

Publikováno v: Journal of Materials Research and Technology, Vol 23, Iss , Pp 1947-1967 (2023)

Two passes of constrained groove pressing (CGP) were conducted on a two-phase Mg–Li alloy followed by temperature-assisted ultrasonic shot peening (TA-USP) with different peening durations and temperatures. The effects of TA-USP and CGP on microstr

Influence of erbium addition on the defects of selective laser-melted 7075 aluminium alloy

Autor: Xuhui Zhang, Zhen Xiao, Wenhui Yu, Chee Kai Chua, Lihua Zhu, Zongshen Wang, Peng Xue, Shuai Tan, Yongling Wu, Hongyu Zheng

Publikováno v: Virtual and Physical Prototyping, Vol 17, Iss 2, Pp 406-418 (2022)

Selective laser-melted (SLMed) 7075 aluminium alloy is prone to cracking. Erbium (Er) could modify the aluminium alloys to prevent cracking in traditional manufacturing processes. In the present study, Er-modified 7075 aluminium alloy powders are pre
