tailieunhanh - Solidification and phase transformations in welding

• Students are required to understand solidification and phase transformations in the weld, which affect the weld microstructure in carbon steels, stainless steels, aluminium alloys and titanium alloys. Suranaree University of Technology Tapany Udomphol Sep-Dec 2007 Introduction Suranaree University of Technology Tapany Udomphol Sep-Dec 2007 Part I: Solidification in carbon steel and stainless steel welds • Carbon and alloy steels are more | Solidification and phase transformations in welding Subjects of Interest Part I Solidification and phase transformations in carbon steel and stainless steel welds Solidification in stainless steel welds Solidification in low carbon low alloy steel welds Transformation hardening in HAZ of carbon steel welds Part II Overaging in age-hardenable aluminium welds Part III Phase transformation hardening in titanium alloys Suranaree University of Technology Tapany Udomphol Sep-Dec 2007 Objectives This chapter aims to Students are required to understand solidification and phase transformations in the weld which affect the weld microstructure in carbon steels stainless steels aluminium alloys and titanium alloys.
