Capillary rheological studies of 17-4 PH MIM feedstocks prepared using a custom CSIR binder system

Author: Machaka, Ronald ; Ndlangamandla, P ; Seerane, Mandy N Date: Feb 2018 This paper reports on an attempt to establish the rheological properties of 17-4 PH stainless steel MIM feedstocks prepared using a proprietary CSIR wax-based binder system. The influence of powder and feedstock characteristics on the rheological ... Read more
Challenges of titanium metal injection moulding

Author: Benson, JM ; Chikwanda, HK Date: Nov 2007 Titanium has fired the imagination of engineers and designers for decades by its ‘ideal’ combination of high strength, low density and good corrosion resistance. However, its application has unfortunately been limited to those niche markets ... Read more
The influence of particle size distribution on the properties of metal-injection-moulded 17-4 PH stainless steel

Author: Seerane, Mandy ; Ndlangamandla, P ; Machaka, Ronald Date: Oct 2016 Metal injection moulding (MIM) is a near-net-shaping powder metallurgy technique suitable for the cost-effective mass production of small and complex components. In this paper, the effects of the metal powder particle size on the final ... Read more

Investigation of the powder loading of gas-atomized Ti6Al4V powder using an ‘in-house’ binder for metal injection moulding

Author: Seerane, MN ; Chikwanda, HK ; Focke, W ; Machaka, Ronald Date: Oct 2013 Powder loading is one of the most critical factors in metal injection moulding (MIM) technology. It largely determines the success or failure of the subsequent MIM processes. A gas-atomized Ti6Al4V powder was investigated to determine an ... Read more
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
Rheological assessment of titanium MIM feedstocks [Journal article]

Author: Benson, JM ; Richter, W ; Chikwanda, HC Date: Mar 2011 Titanium is an exciting structural material that can offer significant strength-to-weight advantages over currently used alloys. However, its Achilles’ heel is its costly, energy-intensive production process that effectively eliminates it ... 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
