| Although the grafted nano-silica brings about an embrittling effect during tensile tests, as revealed by Fig. |
| We conclude that reduced MOR and IB seen in remediated PB are the result of residual oxalic acid either embrittling the fiber or interfering with UF resin adhesion. |
| These effects combine to make phosphorus an extremely effective embrittling agent, even when fracture occurs transgranularly. |
| Because of the high solubilities in niobium and tantalum, these embrittling contaminants normally do not present problems in fabrication. |
| Nickel has a strengthening effect, similar to that of manganese, although more limited because it only acts to reduce the embrittling effect of iron. |
| On other side, the addition of rigid particles to a soft polymer matrix has an embrittling effect on the composite. |
