Statistical analysis of structure loss in Czochralski silicon growth
(111)Si thin layers detachment by stress-induced spallation
In this work, results of controlled detachment of (111) silicon by stress induced spalling (SIS) process, which is based on a gluing on a metallic stressor layer by an epoxy adhesive on top of a silicon substrate, are presented. It is shown that silicon foils mainly (1 × 1) cm2 with different...
Analysis of the Interplay Between Thermo-solutal Convection and Equiaxed Grain Motion in Relation to Macrosegregation Formation in AA5182 Sheet Ingots
Shrinkage induced flow, thermo-solutal convection and equiaxed grain motion are the major transport mechanisms contributing to macrosegregation formation in aluminum alloys produced through Direct Chill casting. Experimental and numerical studies were conducted to provide insight on macrosegregation...

Heat source management in wire-arc additive manufacturing process for Al-Mg and Al-Si alloys
Modelling of wire-arc additive manufacturing process is an effective way for adapting the optimum parameters as well as understanding and managing the sequences of layer-by-layer deposition. Some of these parameters such as toolpath, deposition intervals and heat source power play important roles in...
