Uniaxial tensile response and J integral–resistance behavior of 304L austenitic stainless steel manufactured by laser powder bed fusion process (LPBF) were investigated. The steel undergoes transformation induced plasticity (TRIP) at room temperature, resulting in high fracture toughness (JQ) values...
