ADVANCED SINTERING TECHNIQUES OF ALUMINUM: SPARK PLASMA SINTERING
(2014-08-25)Spark plasma sintering (SPS) of air atomized aluminum powders was conducted in a fundamental investigation of processing and chemical effects on physical and mechanical properties. Five air atomized aluminum powders, one ... -
Consolidation of Aerospace Grade Aluminum 7055 Powder Via PM Technologies
(2016-08-31)The objective of this research was to assess the response of aerospace grade gas atomized aluminum 7055 (Al-8Zn-2.1Mg-2.3Cu-0.2Zr) powder to sinter-forge and SPS-forge styles of powder metallurgy processing. In meeting ... -
Direct Powder Roll Compaction of α- β Titanium Alloys with Al, V, and Fe
(2022-08-12)Compared to other metals, titanium has good corrosion and oxidation resistance, strength-weight ratio, and retains strength at relatively high temperatures. Despite being an excellent engineering material, its cost of ... -
EFFECTS OF IRON AND NICKEL ON THE PROCESSING AND PERFORMANCE OF AN EMERGING ALUMINUM-COPPER-MAGNESIUM POWDER METALLURGY ALLOY
(2012-07-04)Aluminum (Al) powder metallurgy (PM) provides a cost effective and environmentally friendly means of creating lightweight, high performance, near net shape components, relative to conventional casting/die casting technology. ... -
FRICTION STIR PROCESSING OF 2xxx SERIES ALUMINIUM PM ALLOYS
(2020-04-14)Friction stir welding (FSW) is a novel solid-state process known to facilitate the joining of materials that exhibit a poor response to conventional fusion welding technologies. Certain aluminium alloys in the 2xxx series ... -
INFLUENCE OF BLENDED ELEMENTAL ALUMINUM AND TITANIUM-ALUMINUM MASTER ALLOY ADDITIONS ON THE SINTERING BEHAVIOUR OF TITANIUM – 6 ALUMINUM ALLOY
(2016-11-03)Despite their attractive properties Titanium alloys have limited use in automotive applications due to their high cost. Processing low-cost Ti powder sources through a blended elemental or master alloy powder metallurgy ... -
NITI: AN IN-SITU INVESTIGATION OF SINTERING FROM ELEMENTAL POWDERS
(2016-11-04)Ni-Ti powder mixtures mixed to 49 at% Ni : 51 at% Ti were made from high purity Ti – fine Ni (HP mixture), low purity Ti – fine Ni (LP mixture) high purity coarse (RA) Ti – fine Ni (RA mixture) and high purity Ti – coarse ... -
ON A NOVEL METHOD OF INCORPORATING AN INTERNAL STRUCTURE INTO GREEN POWDER METALLURGY COMPACTS USING DIE COMPACTION
(2012-08-09)A novel method of producing die compacted powder metallurgy components with fully en-closed internal structures was developed. The physical characteristics of the compacts were evaluated by measuring bulk density, internal ... -
Sinter-Swage Processing of an Al-Si-Mg-Cu Powder Metallurgy Alloy
(2021-08-26)A powder metallurgy (PM) alloy similar to wrought aluminum alloy 6013 was researched. Alloy variants emphasized systems with/without pre-alloyed manganese and admixed elemental tin powder. Systems with pre-alloyed manganese ... -
THERMOMECHANICAL PROCESSING OF SPARK PLASMA SINTERED ALUMINUM POWDER METALLURGY ALLOYS VIA ASYMMETRIC ROLLING AND UPSET FORGING
(2019-12-16)The research in this study was completed to investigate the effects of thermal-mechanical working on spark plasma sintered (SPS) powder metallurgy (PM) preforms. Two alloys (PA2219 and an Al-Sc-Zr ternary) were considered ...
