Phase, microstructure and mechanical properties evolution of W-Ni-Fe alloy during SPS and HSPS were studied. The microstructural evolution of the 60 mm alloys varied from the edge of the sample to the core of the sample. Results show that the grain size and the hardness vary considerable from the edge to the core of sintered sample of 60 mm sintered using conventional SPS compared to hybrid SPS. Similarly, the hardness also increased from the edge to the core. The 60 mm-HSPS alloy exhibit improved bending strength than the 60 mm-SPS, 1115 MPa and 920 MPa respectively, former being similar to the 30 mm-SPS and HSPS alloys. The intergranular fracture along the W/W grain boundary is the main fracture modes of W-Ni-Fe, however in the 60 mm-SPS alloy peeling of the grains was also observed which diminished the properties. The mechanical properties of SPS and HSPS 93W-4.9Ni-2.1Fe heavy alloys are dependent on the microstructural parameters such as tungsten grain size and overall homogeneity.]]> Thu 22 Aug 2019 20:12:48 SAST ]]> Effect of scanning speed and powder flow rate on the evolving properties of laser metal deposited ti-6al-4v/cu composites https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:20331 Thu 22 Aug 2019 19:02:26 SAST ]]> Effect of starting powder particle size and heating rate on spark plasma sintering of Fe- Ni alloys https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:20792 Thu 22 Aug 2019 18:49:41 SAST ]]> Microstructure and microhardness of 17-4 ph stainless steel made by laser metal deposition https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:21275 Thu 22 Aug 2019 11:51:47 SAST ]]> Property evolution of thermo-mechanically treated reinforcement bar https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:31608 Thu 22 Aug 2019 10:14:25 SAST ]]> Effect of weight per meter of reinforced bar on mechanical properties and microstructure https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:24945 Thu 22 Aug 2019 08:46:33 SAST ]]> Influence of scanning speed on the intermetallic produced in-situ in laser metal deposited TiC/Ti6Al4V composite https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:24415 Thu 20 Jul 2017 09:36:49 SAST ]]> Effect of laser power on the microstructural behaviour and strength of modified laser deposited Ti6Al4V+CU alloy for medical application https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:20577 Thu 09 Mar 2017 10:03:18 SAST ]]> Characterising the brake blocks of a freight rail container wagon https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:20320 Thu 09 Mar 2017 10:01:15 SAST ]]> Influence of tool rotational speed on microstructure and joint strength of friction stir spot welded pure copper https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:21231 Thu 09 Mar 2017 08:52:01 SAST ]]> Microstructural and mechanical properties of spark plasma sintering of Ni2 Cr11Al powders synthesized by mechanical alloying for thermal barrier coating https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:30407 Thu 08 Nov 2018 11:18:39 SAST ]]> Laser metal deposition of Ti6Al4V : a study on the effect of laser power on microstructure and microhardness https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:4896 Sat 16 Sep 2017 00:14:35 SAST ]]> Microstructure evolution and mechanical characterization of friction stir welded titanium alloy Ti–6Al–4V using lanthanated tungsten tool https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:29110 Mon 30 Jul 2018 15:44:36 SAST ]]> Forming behaviour of steel sheets after mechanical and laser beam forming https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:4998 Mon 19 Aug 2019 10:38:28 SAST ]]> Effect of water flow rate on the yield strength of a reinforced bar https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:25198 Mon 19 Aug 2019 09:34:20 SAST ]]> Gas flow rate and powder flow rate effect on properties of laser metal deposited Ti6Al4V https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:4849 Fri 15 Sep 2017 22:53:46 SAST ]]> Effect of scanning speed on the material characterizations of laser deposited titanium alloy and copper https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:26225 Fri 15 Dec 2017 09:33:28 SAST ]]> The influence of scanning speed and number of scans on the properties of laser formed steel https://ujcontent.uj.ac.za/vital/access/manager/Repository/uj:20385 Fri 09 Sep 2016 11:27:53 SAST ]]>
