摘要： Provided is a titanium cast product made of commercially pure titanium, the titanium cast product being produced by electron-beam remelting or plasma arc melting, comprising: a melted and resolidified layer in a range of 1 mm or more in depth at a surface serving as a surface to be rolled, the melted and resolidified layer being obtained by adding one or more kinds of β stabilizer elements to the surface and melting and resolidifying the surface. An average value of β stabilizer element(s) concentration in a range of within 1 mm in depth is higher than β stabilizer element(s) concentration in a base material by, in mass %, equal to or more than 0.08 mass % and equal to or less than 1.50 mass %. As the material containing the β stabilizer element, powder, a chip, wire, or foil is used. As means for melting a surface layer, electron-beam heating and plasma arc heating are used.

摘要： A continuously cast slab with a rectangular cross section, and made of high alloy containing Cr of 20 to 30 mass %, Ni of 30 to 50 mass %, and at least one of Mo and W as Mo+0.5W of 1.5 mass % or more is subjected to blooming and billet-making to yield a round bar having a diameter of 150 to 400 mm as a starting material of the seamless tube. The blooming and billet-making process is performed under a condition satisfying a relation of 1.3≦H/D≦1.8 where a short side length of the cross section of the cast slab is defined as H (mm), and the diameter of the round bar is defined as D (mm). The round bar is pierced-rolled to make a hollow blank; the hollow blank tube is elongation-rolled, and then diameter-adjusting-rolled to make the seamless tube, thereby preventing end cracking during piercing-rolling, and increasing yield.

摘要： A method is provided for producing a clad metal product having a core and a shell of different materials and suitable for use in forming processes. The method comprises the steps of providing a solid hollow shell member comprising a first metal, the shell open at one end and having an inner surface defining a cavity. A molten second metal from a source of molten metal is introduced into the cavity in sufficient quantity to substantially fill the cavity. The molten second metal is permitted to solidify thereby forming a workpiece having a core and a cladding shell of different metals which are sufficiently metallurgically bonded to one another at their interface. The final work product may be heated to rolling temperature and rolled to form a clad article of predetermined configuration.

摘要： Methods and apparatus are described for the plastic deformation of flat rectangular billets. Simultaneous extrusion of two flat rectangular billets through a die having channels of equal cross-sectional area alters billet material structure, texture, and physicomechanical properties without altering billet dimensions. The extrusion system of the present invention prolongs die lifetime, increases punch stability, decreases punch working load and pressure requirements, eliminates the difficulties associated with lubricating movable parts of the die under high pressure and temperature, optimizes use of press space, and provides for automatic and independent ejection of extruded billets from the die. The methods of plastic deformation processing of flat rectangular billets in the present invention allow for the production of a variety of structural, textural, and physicomechanical properties previously unobtainable for large flat rectangular billets.

摘要： A method of rolling a continuous welded billet having weld joints at successive locations along the billet and wherein the continuous welded billet is advanced through roll pairs of successive roll stands. The rolling conditions in two successive stands are adjusted so that when a weld joint is between the two stands compression is produced at the weld joint causing an increase of cross-sectional area at the weld joint. The rolling condition involves superimposing an increase in roll speed in the upstream roll stand compared to the downstream roll stand based on tracking information of the weld joint.
