Overheating of low-alloy steels
International Metals Reviews, 1984AbstractWhen low-alloy steels are reheated to high temperatures for forging, a deterioration in the ambient-temperature mechanical properties after a full heat treatment may be observed. This is linked with the appearance of intergranular facets on the fracture surface.

Metal Science and Heat Treatment, 1967
1. Low-carbon steel 10G2S1D is characterized by low stability of supercooled austenite and low hardenability. 2. The optimum heat treatment is quenching from 960–980°C, with soaking 1.5 min per mm of thickness, and tempering at 660–680°C, with soaking 4–5 min per mm of thickness, and cooling in water or in air.

High-Strength, Low-Alloy Steels
Science, 1980High-strength, low-alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load-bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium,

Superplasticity in low-alloy steels
Metallurgical Transactions A, 1976Superplasticity has been investigated in three carbon-manganese steels with small additions of Nb, V, Al and Ti. Superplasticity was observed from 800 to 1000°C at strain rates from 0.002 to 0.01 min-1. Strain rate sensitivities above 0.7 have been observed; however elongations to fracture are quite low with a maximum value observed of 184 pct.

Corrosion of Carbon and Low Alloy Steels
2010Due to the breadth of the subject, it is impossible to cover comprehensively the whole range of corrosion applications and processes for carbon and low alloy steels. Indeed, for many topics of interest, other chapters elsewhere in this book will provide more detailed, and in-depth, treatments.

Gas-Carburizing Kinetics of a Low-Alloy Steel
Metallurgical and Materials Transactions A, 2009Gas-carburizing kinetics of a low-alloy steel (Pyrowear 53) was investigated by thermogravimetric experiments. Kinetic curves were modeled by adapting the approximate integral method, and the diffusion coefficient of carbon as well as the rate constant of the surface reaction were estimated.

Abstract Steels contain a wide range of elements, including alloys as well as residual processing impurities. This chapter describes the chemical composition of low-alloy AISI steels, which are classified based on the amounts of chromium, molybdenum, and nickel they contain.

Electroslag cladding of low alloy steel with stainless steel
Science and Technology of Welding and Joining, 2002Cladding of a low alloy steel slab with stainless steel was carried out using a modified electroslag remelting technique. It is shown that the thickness of the cladding that can be achieved via electroslag remelting is dependent on the fill ratio used. The effect of power input on the joint profile obtained is reported. A combination of low fill ratio
