Fracture toughness of CaO-$ P_{2} %$ O_{5} $-$ B_{2} %$ O_{3} $ glasses and glass-ceramics determined by indentation
Abstract The fracture toughness, (KIC) of CaO-$ P_{2} %$ O_{5} $-$ B_{2} %$ O_{3} $ glasses and glass-ceramics was investigated using both Vickers indentation and the notched beam technique (NBT). Five representative equations were applied and it was found that for the variation of KIC with $ B_{2}...

| 520 | |a Abstract The fracture toughness, (KIC) of CaO-$ P_{2} %$ O_{5} $-$ B_{2} %$ O_{3} $ glasses and glass-ceramics was investigated using both Vickers indentation and the notched beam technique (NBT). Five representative equations were applied and it was found that for the variation of KIC with $ B_{2} %$ O_{3} $ content, the Lawn and Fuller equation showed the best correspondence with the NBT. The values of fracture toughness obtained from the Lawn and Fuller equation showed the same trend with $ B_{2} %$ O_{3} $ content as that determined by NBT, although the values from indentation were on average 33% lower. The determination of absolute fracture toughness by indentation requires a correction factor which can be obtained by calibration using NBT. A significant increase in KIC occurred after a 37CaO-$ 37P_{2} %$ O_{5} $-$ 20B_{2} %$ O_{3} $-$ 6Al_{2} %$ O_{3} $ (mol%) glass was converted to a glass-ceramic. The much higher KIC for the glass-ceramic measured by NBT (1.32 MN $ m^{−3/2} $) compared with that from indentation (0.89 MN $ m^{−3/2} $) is attributed to internal stresses due to thermal expansion differences between the crystalline and residual glass phases leading to additional microcrack toughening. | ||

Five representative equations were applied and it was found that for the variation of KIC with $ B_{2} %$ O_{3} $ content, the Lawn and Fuller equation showed the best correspondence with the NBT. The values of fracture toughness obtained from the Lawn and Fuller equation showed the same trend with $ B_{2} %$ O_{3} $ content as that determined by NBT, although the values from indentation were on average 33% lower. The determination of absolute fracture toughness by indentation requires a correction factor which can be obtained by calibration using NBT. A significant increase in KIC occurred after a 37CaO-$ 37P_{2} %$ O_{5} $-$ 20B_{2} %$ O_{3} $-$ 6Al_{2} %$ O_{3} $ (mol%) glass was converted to a glass-ceramic. The much higher KIC for the glass-ceramic measured by NBT (1.32 MN $ m^{−3/2} $) compared with that from indentation (0.89 MN $ m^{−3/2} $) is attributed to internal stresses due to thermal expansion differences between the crystalline and residual glass phases leading to additional microcrack toughening.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Polymer</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermal Expansion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fracture Toughness</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Correction Factor</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">B2O3</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">James, P.

Fracture toughness of CaO-$ P_{2} %$ O_{5} $-$ B_{2} %$ O_{3} $ glasses and glass-ceramics determined by indentation |
| abstract |
Abstract The fracture toughness, (KIC) of CaO-$ P_{2} %$ O_{5} $-$ B_{2} %$ O_{3} $ glasses and glass-ceramics was investigated using both Vickers indentation and the notched beam technique (NBT). Five representative equations were applied and it was found that for the variation of KIC with $ B_{2} %$ O_{3} $ content, the Lawn and Fuller equation showed the best correspondence with the NBT. The values of fracture toughness obtained from the Lawn and Fuller equation showed the same trend with $ B_{2} %$ O_{3} $ content as that determined by NBT, although the values from indentation were on average 33% lower. The determination of absolute fracture toughness by indentation requires a correction factor which can be obtained by calibration using NBT. A significant increase in KIC occurred after a 37CaO-$ 37P_{2} %$ O_{5} $-$ 20B_{2} %$ O_{3} $-$ 6Al_{2} %$ O_{3} $ (mol%) glass was converted to a glass-ceramic. The much higher KIC for the glass-ceramic measured by NBT (1.32 MN $ m^{−3/2} $) compared with that from indentation (0.89 MN $ m^{−3/2} $) is attributed to internal stresses due to thermal expansion differences between the crystalline and residual glass phases leading to additional microcrack toughening. |
