Abstract

A process to produce passified Group IVb transition metal based metal particles having a controlled particle size distribution is disclosed which produces particles suitable for metallurgy usage without additional particle size reduction. Such particles are also substantially free of halides and are produced at temperatures considerably below that of arc melting temperatures of Group IVb transition metals and alloys based thereon.

Mechanical Behavior of Titanium-Based Layered Structures Fabricated Using Blended Elemental Powder Metallurgy

Journal Article Markovsky, Pavlo; Savvakin, Dmytro; Ivasishin, Orest; ... - Journal of Materials Engineering and Performance

Mechanical behavior of bilayered structures composed of the layer of Ti-6Al-4 V (wt.%) (Ti-64) alloy and metal matrix composite (MMC) on the base of this alloy reinforced with 5 and 10% (vol.) of either TiB or TiC particles has been studied. Structures were fabricated using blended elemental powder metallurgy and studied by tensile and three-point flexural tests. Mechanical tests were performed on uniform single-layer samples of the alloy as well as individual MMCs. In addition, bilayered structures were also tested in three-point flexural experiment. Posttest fractographic inspections were made using the SEM. The deformation energy was measured based on engineering stress–strainmore »« less

Radiance temperatures (in the wavelength range 523-907 nm) of Group IVB transition metals titanium, zirconium, and hafnium at their melting points by a pulse-heating technique

Journal Article Cezairliyan, A; McClure, J; Miller, A - International Journal of Thermophysics

The melting-point radiance temperatures (at six wavelengths in the range 523-907 nm) of the Group IVB transition metals titanium, zirconium, and hafnium were measured by a pulse-heating technique. The method is based on rapid resistive self-heating of the specimen from room temperature to its melting point in less than 1 s and on simultaneously measuring the specimen radiance temperatures every 0.5 ms with a high-speed six-wavelength pyrometer. Melting was manifested by a plateau in the radiance temperature-versus-time function for each wavelength. The melting-point radiance temperatures for a given specimen were determined by averaging the measured temperatures along the plateau atmore »« less

High-strength powder metallurgy aluminum alloys in glass-forming Al-Ni-Ce-(Ti or Zr) systems

Journal Article Kawamura, Y; Inoue, A; Sasamori, K; ... - Scripta Metallurgica et Materialia; (United States)

Powder metallurgy (P/M) aluminum alloys with high mechanical strengths have been developed by taking advantage of rapid solidification (RS). The improved strengths result from structural modifications such as reduction of segregation, refinement of grain size and increase in solid solubility limit which mainly depend on the amount of undercooling of melt. To produce crystalline alloys with a refined structure, few approaches are considered: the crystallization of an amorphous alloy, the control of cooling rate from melt and the selection of optimum composition for glass-forming alloys. However, these methods are generally attended with a disadvantage for embrittlement. Recently, it has beenmore »« less

Ni{sub 3}Al intermetallic particles as wear-resistant reinforcement for Al-base composites processed by powder metallurgy

Journal Article Diaz, C; Gonzalez-Carrasco, J; Caruana, G; ... - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

The suitability of Ni{sub 3}Al intermetallics as reinforcement for Al-base materials for tribological applications has been investigated. For this purpose, an Al/Ni{sub 3}Al (5 vol pct) composite was prepared by powder metallurgy and tested in air against steel counterfaces at the load range of 45 to 178 N. For comparison, unreinforced Al specimens were processed and tested under the same conditions. Tribological behavior was evaluated by microstructural examination of wear-affected zones and weight-loss measurements of specimens and counterfaces. It was found that a significant amount of Fe-rich oxide particles become incorporated into the Al matrix during wear, forming a crackedmore »« less
