Developing concepts on composition, he creates pieces with larger areas of plain sheet metal and patination in blocks so the viewer can respond emotionally to the base metal. 在构图的概念方面，他运用了大面积的金属片和层叠的薄片，务求令观赏者能够对最底层的金属做出感性的反应。
Both FZ and HAZ have higher microhardness than the base metal has, and microhardness in fusion centre zone is the lowest. 熔合区和热影响区的显微硬度显著高于母材，焊缝中心区在整个焊缝部分硬度最低。
When grinding chrome to finish dimensions, overheating the base metal can create UTM and OTM formations under the chrome. 恢复涂层设计尺寸而打磨部件的镀铬层时，本体金属的打磨过热会造成在镀铬层下形成UTM和OTM。
