steel research international, EarlyView.The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Biography of Are Tsirk (1937-2015): Flintknapper and scholar
Journal of Lithic Studies, 2015 Are Tsirk was as much a scholar as he was a flintknapper. These disciplines were intertwined and expressed in his experimental research, by way of his exploration of fractography, and his replication of stone tools which spanned the archaeological record
