Metal injection moulding of a 17-4 PH stainless steel: A comparative study of mechanical properties

Author: Machaka, Ronald Date: Oct 2018 While the metal injection moulding (MIM) of the precipitation-hardenable 17-4 PH stainless steel has found wide-ranging applications in a number of industries and popularity as a workhorse alloy, data on the as-sintered properties ‘that can ... Read more
Modification of H950 condition for 17-4 PH stainless steel processed by DED

Author: Mathoho, Ipfi ; Arthur, Nana KK ; Tlotleng, Monnamme Date: Feb 2023 The current study embarked on developing the H950 aging condition for 17-4 PH stainless steel that was manufactured through the DED process. The driving force for carrying out this study was that, when the H950 condition was applied to 17-4 ... Read more
X-ray computed microtomography studies of MIM and DPR parts

Author: Muchavi, Noluntu S ; Bam, L ; De Beer, FC ; Chikosha, Silethelwe ; Machaka, Ronald Date: Oct 2016 Parts manufactured through power metallurgy (PM) typically contain pores that can be detrimental to the final mechanical properties. This paper explores the merits of 3D X-ray computed tomography over traditional microscopy for the characterization ... Read more
