The reason for setting it to 4% is that even if the amount of silicon is increased further, the material properties and castability are saturated, and the agitation property is deteriorated.

However, when the metal structure is refined by melting it as in the remelting process, magnesium having a low melting point (650 ° C.) may evaporate and the content may decrease. When the magnesium content decreases, the hardness and strength decrease even if heat treatment is performed, and desired material properties cannot be obtained.

て説明する。Eutectic silicon is hard and brittle, and serves as a starting point for crack initiation and a propagation path, so that elongation is reduced. In addition, the fatigue life of a portion such as an intervalve portion that is repeatedly subjected to thermal stress is reduced. The metal structure has a morphology of eutectic silicon that is continuous along the dendrites, but by reducing the size of the eutectic silicon and distributing it uniformly, cracks due to stress concentration and the propagation of cracks that occur are suppressed. It becomes possible to do. [Cylinder Head Manufacturing Method] Next, a manufacturing process of the diesel engine cylinder head according to the present embodiment will be described.

In order to solve this, when processing the surface of the casting where the drilling of bolts such as the cylinder head is performed in a later process, use a protrusion with a diameter smaller than the hole diameter in the drilling Set to the position where drilling is performed. This allows the product to have no end holes.
