The Characterization of TiC and Ti(C,N) Based Cermets with and without Mo2C
(2014-03-05)Titanium carbide (TiC) and titanium carbonitride (Ti(C,N)) are both common components in hard, wear resistant ceramic-metal composites, or cermets. In this study the intermetallic nickel aluminide (Ni3Al) has been used as ... -
Development and comparison of HVOF and laser DED methods for depositing TiC-Ni3Al based coatings
(2023-08-17)Deposition of TiC-Ni3Al composite coatings by high velocity oxyfuel (HVOF) and directed energy laser deposition (DED) was investigated for enhancements, modifications and/or repairs of steel surfaces with extensive wear ... -
Standardized Process for Filed Estimation of Unconfined Compressive Strength Using Leeb Hardness
(2017-03-22)An investigation of the statistical relationship between Leeb Hardness (“D” type) values (HLD) and unconfined compressive strength values (UCS) for different rock types was conducted. The Leeb hardness test (LHT) procedure ... -
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 ...
