6、凹陷的痕迹。“会不会是我累得没力气了呢?”维尔姆再一次举起锤子，用尽吃奶的力气往新材料上敲，在听到巨大响声的同时，他觉到整个手臂被震得发麻。维尔姆精神为之一振，顾不得手臂疼痛，连忙拾起新材料。它，依然完好无损。坚硬的铝终于诞生了!维尔姆对新材料——铝合金的强度做了估测，证实它的强度比铝高3-5倍。可是，用它制造武器还是不行。“可不可以再提高它的强度呢?”维尔姆立即想到了淬火，因为淬火可以提高钢铁的硬度。维尔姆将铝合金放在炭火中烧。熊熊的火焰将铝合金烧得通红。他将铝合金夹出，很快地浸入水中。顿时，在“咝咝咝”的响声中，烟雾弥漫。维尔姆对淬火后的铝合金的强度进行估测，果

7、然强度又提高了许多。为了以后实验的开展，维尔姆暂时放下手头的淬火工作，又进行含铜和镁的铝合金的炼制工作。待炼得一定数量铝合金后，为慎重起见，维尔姆对原先淬火过的铝合金的强度又进行估测。他惊奇地发现，铝合金的强度又提高了1倍。两次测定的结果为什么相差甚远?难道是测量仪器坏了吗?维尔姆对测量仪器仔细地检查一遍，没有发现什么异常现象。维尔姆想：是不是时间老人在捣鬼呢?经过试验，证实了他的推测：这种铝合金在放置一段时间后，它的强度会逐渐提高。由此，维尔姆也找到了一种最佳热处理方法。这种含少量铜和镁的铝合金，经过淬火，成了比钢铁轻但却与钢铁一样坚固的材料。第1章铝产品现状
