Download or read book An Investigation of the Influence of Deoxidation and Chemical Composition on Notched bar Properties of Semikilled Ship Steel written by H. M. BANT and published by . This book was released on 1952 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formulas for calculating tensile properties and notched-bar transition temperatures were developed from data obtained on a comprehensive series of experimental steels. For a particular strength level, steels with higher manganese-carbon ratios have lower transition temperatures. The influence of nitrogen in raising the strength and transition temperature of semikilled steel was studied. Heats treated with zirconium in amounts ranging from 0.06 to 0.10 per cent were made and tested. Small additions of aluminum to steels with low silicon contents usually lowered the tear-test and Charpy transition temperatures. The presence of titanium in excess of 0.02 per cent seems to increase the transition temperature of both Type A and Type B type ship plate. Increasing the ferritic grain size of a particular steel by austenitizing at increasingly higher temperatures raises the transition temperature.

Available in PDF, EPUB and Kindle. Book excerpt: This report gives the experiences of several steel producers and consumers with vacuum degassing as a melting practice in the manufacture of high-strength steels for critical applications. The parameters involved in determining the effects of melting practice on mechanical properties are outlined. Pertinent melting processes are described and evaluated qualitatively. In presenting the data, vacuum degassing is compared with other melting practices such as conventional air melting and consumable-electrode vacuum-arc remelting (CEVAR). Generally, there is a trend indicating that vacuum degassing is being used in some production applications instead of air-melted or CEVAR material. In terms of higher and more uniform transverse tensile properties and impact strength, longer fatigue life, and improved cleanliness, the CEVAR alloys were the best. Vacuum degassing by any of the various methods resulted in an improvement in properties of air-melted alloys. In some instances it appeared that the quality of CEVAR alloys could be approached when stream degassing or D-H (Dortmund-Horder) treatment was applied to air melts. Recommendations are given for additional investigations on the effects of melting practice on mechanical properties of premium-quality steels. (Author).
