Editing Diamond (section)

==== Elasticity and tensile strength ====
Usually, attempting to deform bulk diamond crystal by tension or bending results in brittle fracture. However, when single crystalline diamond is in the form of micro/nanoscale wires or needles (~100–300{{nbsp}}nanometers in diameter, micrometers long), they can be elastically stretched by as much as 9–10 percent tensile strain without failure,<ref>{{cite journal | vauthors = Dang C, Chou JP, Dai B, Chou CT, Yang Y, Fan R, Lin W, Meng F, Hu A, Zhu J, Han J, Minor AM, Li J, Lu Y | display-authors = 6 | title = Achieving large uniform tensile elasticity in microfabricated diamond | journal = Science | volume = 371 | issue = 6524 | pages = 76–78 | date = January 2021 | pmid = 33384375 | doi = 10.1126/science.abc4174 | doi-access =  | bibcode = 2021Sci...371...76D | s2cid = 229935085 }}</ref> with a maximum local tensile stress of about {{nowrap|89–98 GPa}},<ref>{{cite journal | vauthors = Banerjee A, Bernoulli D, Zhang H, Yuen MF, Liu J, Dong J, Ding F, Lu J, Dao M, Zhang W, Lu Y, Suresh S | display-authors = 6 | title = Ultralarge elastic deformation of nanoscale diamond | journal = Science | volume = 360 | issue = 6386 | pages = 300–302 | date = April 2018 | pmid = 29674589 | doi = 10.1126/science.aar4165 | doi-access =  | bibcode = 2018Sci...360..300B | s2cid = 5047604 }}</ref> very close to the theoretical limit for this material.<ref>{{cite journal | vauthors = LLorca J | title = On the quest for the strongest materials | journal = Science | volume = 360 | issue = 6386 | pages = 264–265 | date = April 2018 | pmid = 29674578 | doi = 10.1126/science.aat5211 | arxiv = 2105.05099 | s2cid = 4986592 | bibcode = 2018Sci...360..264L }}</ref>
