The effects of ultrasonics on the process of solidification have been investiga(?)d in six pure metals (Zn, Cd, Sn, Pb, Sb, and Bi), a Pb-Sn (50%) eutectic alloy nd an Sb-Bi (10%) alloy. It has been found that:(1) ultrasonics reduce the cooling rate and lengthen the time of solidifi(?)tion;(2) ultrasonics reduce degree of supercooling;(3) ultrasonics refine the cast structure and the optimum power imput varies with metal.It is suggested that the change of cooling curve is due to the facs that:(1) the ultrasonic...

选择了鋅、鎘、錫、鉛、銻和鉍六种純金属,一种鉛-錫(50%重量百分数)共晶型合金和一种銻-鉍(10%重量百分数)固溶体型合金作研究对象,着重研究了超声波对它們凝固过程的影响,并且从其中选取鋅、鎘、銻、鉍和銻-鉍合金观察了晶粒細化和超声波的关系。結果是:超声波使所有这些金属与合金的冷却速度減緩和凝固时間延长,对于有效冷度的銻、鉛-錫和銻-鉍合金的过冷度减小,一般情况下,超声波可使宏观晶粒細化,随功率增加晶粒細化随金属而异。所有这些是由于超声波在金属中传播时,声能变热能和使欲凝固分子做平行于結晶面振动的結果。

The world-famous Western Han "Magic Bronzc Mirror", the Chinese aneient artistic curio, has the property of "Light-Penetration". On the basis of the theory of solidification and with the application of the theory of elasticity, the basic cause of "Light-Penetration Effect" being the residual stresses of the edgc ring of the Mirror is explained in this paper. From experimental mechanical analysis, the quantitative vatlues of the residual stresses are given. The stresses on the back surface of the shallow spherical shell of the mirror are calculated and compared with the experimental values as well.

Oxide inclusions, oxide shuts and contraction cracks are the main casting defects of large marine propellers (φ5000mm, gross weight~20). Investigations of the formation of the defects were carried out both in production scale and in the laboratory. Temperature measurements with thermocouples show that the propeller solidifies directionally from the tip of the blade to the boss and the riser solidifies finally. And the rim part of the blade begins to solidify immediately after being filled. The flow pattern of...

Oxide inclusions, oxide shuts and contraction cracks are the main casting defects of large marine propellers (φ5000mm, gross weight~20). Investigations of the formation of the defects were carried out both in production scale and in the laboratory. Temperature measurements with thermocouples show that the propeller solidifies directionally from the tip of the blade to the boss and the riser solidifies finally. And the rim part of the blade begins to solidify immediately after being filled. The flow pattern of the liquid metal in the mould was investigated through a scale model (Froude model). The mathematical relationship to realize the analogue simulation is , where Vm and Vp, are the corresponding velocities of the fluids in the model and in the prototype. The cracking tendency of the Al-Mn-brass subjected to thermal stress was investigated through a test bar with different diameters solidifing and cooling under constrained condition. Results of both the above experiments and the measures taken in production scale to eleminate the casting defects show that the oxide and dross inclusions formed during pouring are the primary cause of the casting defects and the thermal stress developed after solidification tears up the metal along the oxide inclusions. And the directional solidification of the propeller favours the development of the thermal stress.
