摘要：

Herein, we have performed J-Resistance multi-specimen fracture toughness testing of hot isostatically pressed (HIP'd) and forged 304L austenitic stainless steel, tested at elevated (300 degrees C) and cryogenic (- 140 degrees C) temperatures. The work highlights that although both materials fail in a pure ductile fashion, stainless steel manufactured by HIP displays a marked reduction in fracture toughness, defined using J(0.2BL), when compared to equivalently graded forged 304L, which is relatively constant across the tested temperature range.
