Outer side sill member includes an upper wall section slanting upward in a horizontal, outer-to-inner direction, and a lower wall section slanting downward in the horizontal, outer-to-inner direction. At least one of upper and lower wall sections of the outer side sill member has a channel-shaped bead extending along the side sill, so that the side sill has a polygonal closed sectional shape extending in the front-rear direction of the vehicle. The bead has a bottom portion having a width greater than a vertical dimension in a direction orthogonal to the surface of the bottom portion. Each of bulkheads, partitioning the interior of the side sill, is fixedly joined to the outer side sill member with its recessed edge portion substantially fittingly engaging with the bottom portion of the depressed wall portion of the outer side sill member.

Vehicular side body structure

A billet for a thixocasting process and a thixocasting process using the billet allows casting using a thixocasting process to be realized at low production cost without permeation of an oxide film to the inside of the billet in injection molding. In a billet used for a thixocasting process continuously cast by intermittently drawing out, the interval of the oscillation marks is 10 mm or less and the maximum tilt angle of the oscillation marks relative to a cross section which is at a right angle to the drawing out direction is 45&#xb0; or less.

Billet, horizontal continuous casting process, and thixocasting process

An iron based alloy material for a thixocasting process and a method for casting the material which extends the service life of dies by inhibiting solidification contraction, and in which casting defects such as size variations and cracks can be inhibited. The material comprises 1.6 wt %&#x2266;C&#x2266;2.5 wt % and 3.0 wt %&#x3c;Si&#x2266;5.5 wt %, and a carbon equivalent (the value of CE) defined as 'C(wt %)+&#x2153;Si(wt %)' of 2.9 to 3.5. This material is made to be in a half-melted state with 35 to 50 wt % of a solid phase to be cast under a pressure load.
