美国国家标准与技术研究所冶金学家蒂莫西·福克通过检测得出结论：如果泰坦尼克号游轮使用的铆钉更坚固一些，游轮的外壳撞上冰川后的裂缝就会小一些，游轮浮在水面上的时间就会更长一些，从而使数百人被搭救而免于葬身海底。今年年初，他对从泰坦尼克号沉船上打捞起来的许多 Timothy Fork, a metallurgist at the National Institute of Standards and Technology in the United States, concluded that if the rivets used on the Titanic cruise ship are more sturdy, the cracks in the shell of the cruise ship after it hits the glaciers will be smaller and the cruise ship will float. The time on the water will be longer, so that hundreds of people will be rescued from the bottom of the sea. Earlier this year, he took many of the salvage from the Titanic shipwreck.
