Copper Precipitation Hardened, High Strength, Weldable Steel
Steel containing 0.03% carbon, 1.35% copper and 0.84% nickel had yield strength in the 540-625 MPa (78-90 Ksi) range depending on thickness, ultimate tensile strength in the 625-690 MPa (90100 Ksi) range, and 25-30% elongation when air cooled after hot rolling. No brittle heat-affected zone was formed during manual or automatic submerged arc welding without pre-heating or postheating. The fract...
متن کاملThe Effect of Controlled Thermo Mechanical Processing on the Properties of a High Strength Steel
In this paper, an ultra low carbon High Strength Low Alloy Grade Steel was subjected to a two-step forging process and this was followed by different post cooling methods. The highest strength was obtained at a faster cooling rate due to the highly dislocated acicular ferrite structure with the fine precipitation of microalloying carbides and carbonitrides. At a slow cooling rate, the strength ...
متن کاملTHE KINETIC OF PRECIPITATION REACTIONS IN A RAPIDLY AGED HIGH ALLOY HIGH STRENGTH STEEL
This study was launched to investigate the effects of heating rate and aging parameters on the kinetic of precipitation reactions in a high alloy high strength steel having Ni, Co, Mo and Ti. For this purpose, as quenched specimens were subjected to three types of aging methods with different heating rates. These methods consisted of aging in Pb bath, salt bath, and furnace at different aging c...
متن کاملStrengthening steel bridges with new high modulus CFRP materials
This paper presents the details and relevant findings of an experimental program which was conducted in three phases to investigate the behavior of steel-concrete composite bridge girders strengthened with new high modulus carbon fiber reinforced polymer (HM CFRP) materials. In the first phase, the feasibility of various lIM CFRP strengthening systems was examined. The second phase investigated...
