Abstract : Voids have been found to form around carbide particles in a martensitic stainless steel and a low alloy steel during working. The voids are metastable in austenite at high temperatures and result in a considerable refinement of austenite grain size by acting as barriers to grain growth. Deformation in both the austenitic and martensitic conditions results in void formation. (Author)
