（本刊讯）日本应用聚冷、聚热和压轧的综合方法制造出高强度、耐腐蚀的铝材．科研人员把熔化后凝固为板状的铝放入液氮槽中，让其在—１９６℃环境下急剧冷却，并以很大的压力对它进行压轧，使铝板内部聚积应变能量，然后再急剧加热。这样，铝的金属晶粒就会缩小到３５μm以下 (Ben Kanxun) Japan’s application of poly-cold, heat and pressure of the integrated method of manufacturing high strength, corrosion-resistant aluminum. Researchers put the melted solidified into a plate-shaped aluminum into the liquid nitrogen tank, let it cool rapidly in the environment of -196 ℃, and it was pressed with great pressure to make the internal accumulation of strain energy aluminum plate, and then Rapid heating. In this way, aluminum metal grains will be reduced to 35μm or less
