This book was released on 1964 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies to develop maraging-steel experimental HY-180/210 filler metals indicated that aluminum and titanium nonmetallic inclusions may significantly reduce the toughness of maraging steel weld metals. Therefore, a program was initiated to determine the effects of composition on the mechanical properties of Ni-Cr-Mo-Co experimental HY-180/210 weld metals that contained no aluminum or titanium. The effects of carbon (0.02 to 0.30%), nickel (4.0 to 20.0%), chromium (0.0 to 6.0%), molybdenum (0.0 to 6.0%), and cobalt (0.0 to 8.0%) on the mechanical properties of 32 statistically selected Ni-Cr-Mo-Co filler metals (deposited with the TIG process) were evaluated. The results indicated that the microstructures of the Ni-Cr-Mo-Co as-deposited weld metals consisted of martensite and retained austenite (0 to 88%) and that large amounts of retained austenite caused a large loss in weldmetal strength and toughness.

This book was released on 1963 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies to develop an HY-130/150 submarine-hull steel indicated that a quenched and tempered Ni-Cr-Mo or Ni-Cr-Mo-V steel containing about 5% Ni appeared very promising for this application. However, the hardenability of the steels studied was too low for 4-in. thick plates, and the temperability of the steels without vanadium was unsatisfactory. Therefore, the effects of variations in manganese, chromium, molybdenum, and vanadium on the hardenability, mechanical properties, and temperability of ten vacuum-melted, vacuum-carbon-deoxidized 5Ni-Cr-Mo steels were determined on 1/2-in. thick plates that were water-quenched from 1500 F and tempered to simulate light-gage plates and that were blower-cooled from 1500 F and tempered to simulate the heat treatment at the midthickness of a water-quenched 4-in. thick plate.

Available in PDF, EPUB and Kindle. Book excerpt: Nonconventional heat treatments were designed to improve the mechanical properties of these martensitic steels. Results show that the as-quenched structures of both steels consist mainly of dislocated martensite. In the boron-free steel, there are more lath boundary retained austenite films. The boron-treated steel shows higher strengths at all tempering temperatures but with lower Charpy V-notch impact energies. Both steels show tempered martensite embrittlement when tempered at 350°C for 1 hour. The properties above 500°C tempering are significantly different in the two steels. While the boron-free steel shows a continuous increase in toughness when tempered above 500°C, the boron-treated steel suffers a second drop in toughness at 600°C tempering. Transmission electron microscopy studies show that in the 600°C tempered boron-treated steel large, more or less continuous cementite films precipitate at the lath boundaries, which are probably responsible for the embrittlement. The differences in mechanical properties at tempering temperatures above 500°C are rationalized in terms of the effect of boron-vacancy interactions on the recovery and recrystallization behavior of these steels. Boron seems to impair room temperature impact toughness at low strength levels but not at high strength levels. By simple nonconventional heat treatments of the present alloys, martensitic steels may be produced with quite good strength-toughness properties which are much superior to those of existing commercial ultra-high strength steels. It has also been shown that the as-quenched martensitic steels need not be brittle and in fact very good combinations of strength and toughness can be obtained with as-quenched martensitic steels. 56 fig., 5 tables, 75 references.

This book was released on 1963 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies to develop a submarine-hull steel that would meet the U.S. Navy requirements for an HY-130/150 steel indicated that a 5 1/4Ni-Cr-Mo-V steel appeared promising except that the hardenability of this steel was too low for use as 4-in.-thick plates. Therefore, a preliminary study was initiated on 5Ni-Cr-Mo steels to establish the range of hardenabilities required to obtain the desired microstructure and mechanical properties in 1/2-in.-thick plates air-cooled to simulate the cooling at the center of a water-quenched plate about 6 inches thick. The results showed that tye yield strengths of 1/2-in.-thick air-cooled plates were significantly lower than those of 1/2-in.thick water-quenched plates when the hardenability index was about 15, but that the yield strengths of the air-cooled plates were only slightly lower than those of the water-quenched plates at hardenability indices of 29 and higher. However, even at the higher hardenability values, the notch toughness of the aircooled plates was significantly lower than that of the water-quenched plates. (Author).
