Bending Fatigue of Surface Densified Gears | Gear .

Reference wrought steel (AISI 8620) gears were manufactured to the same geometry by hobbing and shaving. Both sintered and wrought steel gears were gas carburized and oil quenched. The endurance limit in bending fatigue of surface densified gears is compared to that of conventional wrought steel gears.

Fatigue Technical Publications. 193. Chromium Steels for High Performance PM Applications: Chromium steels have long dominated the landscape of the wrought industry because of their high performance capabilities at modest cost levels. Historically, chromium steels have had difficulty penetrating the powder metallurgy market because of oxidation issues.

NTN develops High-strength “Sintered Alloy”-Hangzhou .

For replacement of steel machine parts NTN Corporation (hereafter, NTN) has developed a high-strength sintered alloy with a density of 7.6 g/cm3 or more and an endurance ...

RESEARCH ON THE EXISTENCE OF BORON NITRIDE EXISTENCE IN .

The ball joint can be manufactured using an AISI-SAE 5140 steel. At it has been revealed in [2] the microstructure of the ball has been formed mainly by tempered martensite with acicular grains of ferrite on the grain boundaries. Such presence of tempered martensite indicates that the material endured a heat treatment of quenching and tempering.

Tooth root bending fatigue strength of small-module sinter .

ABSTRACTThe present paper is aimed at investigating the effect of the sinter-hardening treatment in improving the tooth root fatigue resistance of gears obtained by Powder Metallurgy. The gears were produced using two types of low-alloyed partially diffused steel powders, Distaloy DC and Distaloy DH (Höganäs AB, Sweden), that were conventionally sintered as well as sinter-hardened.

Dynamic properties of high-density low-alloy PM steels .

ABSTRACTPM steels with density higher than 7.5 g cm−3 were prepared from binder-treated powder, and the effects of alloying elements and microstructure on dynamic performance were studied. Although the addition of 1.5 wt-% Cu improves the tensile strength, it impairs toughness of the alloy by the formation of low-toughness pearlite. The 0.5 wt-% Cr addition promotes the formation of Ni-rich ...

Sintering - Wikiped

Sintering or frittage is the process of compacting and forming a solid mass of material by heat[1] or pressure[2] without melting it to the point of liquefaction. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms in the materials diffuse across the ...

Rolling contact fatigue behavior of sintered and hardened .

The contact stress versus number of cycles to failure data showed that the wrought steel had a very high endurance limit under rolling contact fatigue compared to the sintered steels investigated. Rolling contact fatigue behavior was found to depend on the porosity present in the material.

Metal Glossary - steel-tube.c

(1) In heat treatment, reheating hardened steel or hardened cast iron to some temperature below the eutectoid temperature for the purpose of decreasing the hardness and increasing toughness. The process also is sometimes applied to normalized steel. (2) In tool steels, “temper” is sometimes used, but unadvisedly, to denote the carbon content.

stresses. Optimized peening parameters have been shown to raise the endurance limit of sintered steel alloys by 22% and the fatigue life by a factor of ten (Fig. 7) This suggests that highly stressed automotive components such as gears and connecting rods should be considered good candidates for sintered steel.

Neodymium magnet - Wikiped

A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. Developed independently in 1982 by General Motors and Sumitomo Special Metals, neodymium magnets are the strongest type of permanent magnet commercially ...
