In-situ simulation of HTS - formation Parameters: Steel composition,solidification time, strain, strain rate.Pierer, R. and C. Bernhard: AISTech 2010, Pittsburg, USAPRICM8 Bernhard 19 In-situ simulation of HTS - formation Results confirm proposed mechanism: In contrast to thecommon opinion no clear boundary between „Cracks“ and „Nocracks“ exists. An increasing strain results in an increasingnumber of HTS and an more pronounced enrichment.Bernhard, C. and R. Pierer:Solidification 2007, Sheffield, UKPRICM8 Bernhard 20
