Abstract
The effect of tailored microstructures in 0.5 wt% CaO added AZ31 on tensile, high-cycle fatigue, and fatigue crack growth properties was examined. By adding CaO, the average grain size (AGS) was significantly reduced from 4.25±2.32 μm (conventional AZ31) to 2.42±1.60 μm (CaO-AZ31). The fineprecipitates of CaO-AZ31 were more evenly distributed.....

DOI:
https://doi.org/10.3365/KJMM.2020.58.3.151
Abstract
Al 3003 alloy was manufactured by strip casting process, and the effect of post heat-treatment on tensile and fatigue properties was investigated. The strip cast Al 300 alloy exhibited a unique globular shaped rapid-cooled solidification structure, and the microstructural characteristic remained after heat-treatment. Asstrip cast (F) and heat-treated (O) alloys.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.3.138
Abstract
This study investigated and compared the tensile and high-cycle fatigue properties of AISI 1045 steel and Cr electroplated AISI 1045 steel. First, tensile and fatigue specimens were machined from AISI 1045 steel (substrate), and two kinds of Cr electroplating layers with different layer thickness were applied. The substrate, AISI 1045.....
