原标题:今年中国已有7种高端钢材实现全新突破,面向新能源汽车、人形机器人等新兴赛道IT之家 8 月 24 日消息,据央视新闻客户端 8 月 22 日报道,我国钢铁产量连续多年位居世界首位。今年以来,钢铁企业依托全国重点实验室,聚焦高端特种钢材持续发力,不断实现核心技术突破,
一大批高端钢材实现了自主量产。 The Nobel Foundation on Saturday withdrew its invitation for representatives of Russia, Belarus and Iran to attend this year's Nobel Prize award ceremonies after the decision announced a day earlier "provoked strong reactions."Several Swedish lawmakers said Friday they would boycott this year's Nobel Prize award ceremonies in the Swedish capital, Stockholm, after the private foundation that administers the prestigious awards changed its position from a year earlier and invited representatives of the three countries to attend, saying it "promotes opportunities to convey the important messages of the Nobel Prize to everyone."Some of the lawmakers cited Russia's war on Ukraine and the crackdown on human rights in Iran as reasons for their boycott. Belarusian opposition figure Sviatlana Tsikhanouskaya on Friday called on the Swedish Nobel Foundation and the Norwegian Nobel Committee not to invite representatives of Belarusian President Alexander Lukashenko's "illegitimate regime to any events."
On Saturday, she welcomed the Nobel Foundation's decision. She told The Associated Press that it was "a clear sign of solidarity with the Belarusian and Ukrainian peoples.""This is how you show your commitment to the principles and values of Nobel," Tsikhanouskaya said.
Ukrainian Foreign Ministry spokesperson Oleh Nikolenko called the decision a "victory for humanism.""Thank you to everyone who demanded that justice be restored," he wrote on Facebook, adding that "a similar decision" should be made regarding the attendance of Russian and Belarusian ambassadors at celebrations taking place in Norway following the ceremony in Sweden.Swedish Prime Minister Ulf Kristersson, who said Friday he wouldn't have allowed the three countries to participate in the award ceremonies, was also happy with the decision. He posted on social media platform X, formerly known as Twitter, that "the many and strong reactions show that the whole of Sweden unambiguously stand on Ukraine's side against Russia's appalling war of aggression."The foundation said Saturday it recognized "the strong reactions in Sweden, which completely overshadowed this message" and therefore it had decided not to invite the ambassadors of Russia, Belarus and Iran to the award ceremony in Stockholm.
However, it said that it would follow its usual practice and invite all ambassadors to the ceremony in the Norwegian capital, Oslo, where the Nobel Peace Prize is awarded.Saturday's announcement was widely praised in Sweden by politicians. Even the Swedish Royal House reacted with spokeswoman Margareta Thorgren saying, as quoted by newspaper Aftonbladet, that "we see the change in the decision as positive". She added that King Carl XVI Gustaf was planning to hand out this year's Nobel awards at ceremonies in Stockholm "as before."This year's Nobel prize winners will be announced in early October. The laureates are then invited to receive their awards at glittering prize ceremonies on Dec. 10, the anniversary of award founder Alfred Nobel's death in 1896.
。钢材如何做到强度过硬,还能抵御海水腐蚀?在河北唐山的钢铁实验室,记者找到了答案。

二 | 钢材加工过程中会产生易导致材料脆化的碳化物,科研人员通过调控钢材原子结构,将碳化物有效包裹。

三 | 研究人员给记者算了一笔账,一台海上风电机要用钢数百吨,换上这种高性能钢,钢板可以做得更薄,合金用量也大幅减少。如今,不只在海上,我国已经搭建起覆盖深海装备、舰船制造、航空航天等多场景的高端钢材自主研发量产体系,从材料配方、轧制工艺到批量生产实现全链条自主可控。
